Definitions
- the invention relates to a lamp, in particular an outdoor lamp, which has a device for attachment to a lamp post, which allows to position the lamp relative to the mast in different inclinations.
- a mast mounting which allows a lamp head to pivot relative to the mast, can be carried out.
- an outdoor lamp is known with a device for mast mounting, which also allows adjusting the angle of inclination relative to the horizontal.
- the adjustment mechanism has been integrated into the luminaire housing. He provides a curved mounting flange, which has slots through which the lamp housing can be fixed in different angular positions by means of screws.
- the adjustment mechanism only allows a pivoting of the lamp by a few degrees. The adjustment range can not be increased because the contact surface on the lamp housing, in which the flange is screwed, includes only a short circular section, which is determined by the shape of the housing.
- the attachment mechanism is based on a frictional engagement between the attachment flange and the luminaire housing. So that the frictional connection can safely carry even heavy luminaire housing, high clamping forces must be applied by a correspondingly high number of screw connections between the mounting flange and the housing.
- FR 2 723 428 A1 discloses a connection device between a lamppost and a lamp.
- the luminaire has a housing with U-shaped cutouts, which have internal teeth on a partial area.
- Continuous sprockets are provided on a lamp post on two opposite sides, on which the internal teeth of the housing cut-outs can act to stabilize the lamp in a desired position. Further, a clamping mechanism is provided to fix the lamp in position.
- US 2007/014115 A1 discloses a pivotable support mechanism for a light housing which houses a light source.
- the pivoting mechanism comprises holding elements, each with two arms, which surround an end section of a pivotable region of the luminaire in the manner of a clamp.
- the arms are toothed with the rotatable element disposed therein. By elastically deflecting the arms, the rotatable member can slide over the teeth to adjust the lamp.
- DE 10 2007 056 280 B3 discloses a vehicle lamp.
- a lamp cap is accommodated in a yoke-like receiving part, wherein the lamp cap has a smaller width than the receiving part, so that the lamp cap is displaceable within the receiving base.

- the receiving space for the bearing element is integrated into the housing or a mast stoolen component, so that both the design and the functionality advantages over mast fastenings are given, which have an exposed hinge point.
- a clamping device which is adapted to fix the positive connection between the bearing element and the receiving space in the housing in one of the selected angular positions.
- the clamping device may have a screw thread according to an embodiment of the invention.
- the clamping device may also comprise a spring.

- the housing is formed of a plurality of parts, each comprising a surface portion of the receiving space.
- the receiving space is bounded by two or more separate bearing shells, each surrounding a part of the circumference of the bearing element. This construction has the advantage that the receiving space around the bearing element can be almost completely closed except in the area in which the bearing element receives the lamp post or has a projection for receiving the lamp element.
- the positive connection between the bearing element and the receiving space is formed according to an embodiment of the invention by a toothing complementary elevations and depressions in a surface regions of the bearing element and in a surface region of the receiving space.

Aus der Druckschrift
Aufgabe der vorliegenden Erfindung ist es, eine Leuchte mit einstellbarer Mastbefestigung zur Verfügung zu stellen, welche einen großen Einstellbereich und eine sichere Handhabung ermöglicht.Object of the present invention is to provide a lamp with adjustable mast attachment available, which allows a large adjustment range and safe handling.
Erfindungsgemäß wird die Aufgabe gelöst durch eine Leuchte nach Anspruch 1.According to the invention the object is achieved by a luminaire according to claim 1.
Die Festlegung des Lagerelements in dem Gehäuse oder einem mit dem Mast verbundenen Bauteil erfolgt durch einen Formschluss, der in mehreren Winkelstellungen gebildet werden kann. Ein Formschluss ist zum Halten schwerer Leuchten geeignet ohne die Notwendigkeit von sehr starken Klemmkräften, wie sie zur Bildung eines Rückschlusses notwendig sind. Ferner ist der Aufnahmeraum für das Lagerelement in das Gehäuse oder einem mastseitigen Bauteil integriert, so dass sowohl vom Design als auch von der Funktionalität Vorteile gegenüber Mastbefestigungen gegeben sind, die eine offenliegende Gelenkstelle aufweisen.The determination of the bearing element in the housing or a component connected to the mast is effected by a positive connection, which can be formed in a plurality of angular positions. A positive connection is suitable for holding heavy lights without the need for very strong clamping forces, as they are necessary to form a conclusion. Further, the receiving space for the bearing element is integrated into the housing or a mastseitigen component, so that both the design and the functionality advantages over mast fastenings are given, which have an exposed hinge point.
Erfindungsgemäß ist eine Klemmvorrichtung vorgesehen, die dafür eingerichtet ist, den Formschluss zwischen dem Lagerelement und dem Aufnahmeraum im Gehäuse in einer der ausgewählten Winkelstellungen festzulegen. Die Klemmvorrichtung kann gemäß einer Ausführungsform der Erfindung ein Schraubgewinde aufweisen. Alternativ kann die Klemmvorrichtung auch eine Feder umfassen. Eine Feder weist den Vorteil auf, dass sie eine konstante Kraft auf die in Eingriff zu bringenden Teile ausübt. Ein Schraubgewinde hat demgegenüber den Vorteil, dass durch ein hohes Drehmoment wesentlich größere Klemmkräfte aufgebracht werden können. Gemäß einigen Ausführungsformen der Erfindung ist auch eine Kombination zwischen einer Feder und einem Schraubmechanismus als Klemmvorrichtung vorgesehen. In diesem Fall kann durch Erhöhen des Drehmoments an dem Schraubgewinde die Feder zusammengedrückt werden, so dass die Klemmkraft, welche die Feder auf die in Eingriff zu bringenden Teile aufbringt, erhöht wird. Zum Lösen der Klemmvorrichtung kann die Verschraubung soweit entgegen der Federkraft gelöst werden, bis die Klemmkraft soweit reduziert ist, dass ein Drehen des Leuchtengehäuses gegenüber dem Lagerelement in dem Aufnahmeraum möglich ist.According to the invention a clamping device is provided, which is adapted to fix the positive connection between the bearing element and the receiving space in the housing in one of the selected angular positions. The clamping device may have a screw thread according to an embodiment of the invention. Alternatively, the clamping device may also comprise a spring. A spring has the advantage that it exerts a constant force on the parts to be engaged. A screw thread has the advantage that much higher clamping forces can be applied by a high torque. According to some embodiments of the invention, a combination between a spring and a screw mechanism is also provided as a clamping device. In this case, by increasing the torque on the screw thread, the spring can be compressed, so that the clamping force applied to the parts to be engaged by the spring is increased. To release the clamping device, the screw can be released so far against the spring force until the clamping force is reduced to the extent that rotation of the lamp housing relative to the bearing element in the receiving space is possible.
Gemäß einer Ausführungsform der Leuchte umfasst die Klemmvorrichtung einen Stift, insbesondere einen Gewindestift und/oder einen federbelasteten Stift, der in dem Gehäuse so gelagert ist, dass er mit einer Spitze in den Aufnahmeraum hineinreichen kann, um den Formschluss mit dem Lagerelement zu bilden. Beispielsweise kann auf dem Lagerelement eine Abfolge von Vertiefungen vorgesehen sein, in die der Stift zur Festlegung des Formschlusses eindringt. Vorzugsweise ist die Spitze des Stifts und die Vertiefung abgerundet oder kegelförmig ausgeführt, so dass sich beim Einfügen des Stifts in die ausgewählte Vertiefung der Formschluss selbständig zentriert.According to one embodiment of the lamp, the clamping device comprises a pin, in particular a threaded pin and / or a spring-loaded pin, which is mounted in the housing so that it can extend with a tip into the receiving space to form the positive connection with the bearing element. For example, may be provided on the bearing element, a sequence of recesses into which the pin penetrates to determine the positive connection. Preferably, the tip of the pin and the recess is rounded or conical, so that when inserting the pin in the selected recess of the positive locking centered automatically.
Gemäß einer Ausführungsform ist das Gehäuse aus mehreren Teilen gebildet, die jeweils einen Oberflächenabschnitt des Aufnahmeraums umfassen. Gemäß der Erfindung wird der Aufnahmeraum durch zwei oder mehr separate Lagerschalen begrenzt, welche jeweils einen Teil des Umfangs des Lagerelements umgeben. Diese Konstruktion hat den Vorteil, dass der Aufnahmeraum um das Lagerelement fast vollständig geschlossen sein kann außer in dem Bereich, in welchem das Lagerelement den Leuchtenmast aufnimmt oder einen Ansatz zur Aufnahme des Leuchtenelements aufweist.According to one embodiment, the housing is formed of a plurality of parts, each comprising a surface portion of the receiving space. According to the invention, the receiving space is bounded by two or more separate bearing shells, each surrounding a part of the circumference of the bearing element. This construction has the advantage that the receiving space around the bearing element can be almost completely closed except in the area in which the bearing element receives the lamp post or has a projection for receiving the lamp element.
Der Formschluss zwischen dem Lagerelement und dem Aufnahmeraum ist gemäß einer Ausführungsform der Erfindung durch eine Verzahnung komplementärer Erhöhungen und Vertiefungen in einem Oberflächenbereichen des Lagerelements und in einem Oberflächenbereich des Aufnahmeraums gebildet. Die Oberflächenbereiche, welche den Formschluss eingehen, können an der Umfangsfläche des walzenförmigen Lagerelements gebildet sein. Die Klemmvorrichtung kann beispielsweise auf die zwei oder mehr Teile des Gehäuses, welche den Aufnahmeraum umgeben, einwirken, um den Formschluss zwischen der Umfangsfläche des walzenförmigen Lagerelements und dem angrenzenden Oberflächenbereich des Aufnahmeraums zu bilden. Gemäß einer alternativen Ausführungsform wirkt der Formschluss zwischen einem Oberflächenabschnitt an einer oder an beiden Stirnseiten des walzenförmigen Lagerelements und der Klemmvorrichtung, die an der gegenüberliegenden Fläche des Lagerraums im Gehäuse vorgesehen ist. Diese Ausführungsform erlaubt es, das Gehäuse im Bereich des Aufnahmeraums aus einem Stück herzustellen, weil es nicht notwendig ist, dass das walzenförmige Lagerelement in Umfangsrichtung um mehr als 180° vom Aufnahmeraum umgeben ist. Das walzenförmige Lagerelement kann durch eine Achse oder durch Bolzen in axialer Richtung in dem Aufnahmeraum drehbar gelagert sein. Der Formschluss zur Blockierung der Drehung kann bei dieser Ausführungsform zwischen dem Aufnahmeraum und dem Lagerelement entweder in Richtung parallel versetzt zur Drehachse auf die Stirnseite des Lagerelements oder in radialer Richtung auf die Umfangsfläche des walzenförmigen Lagerelements wirken.The positive connection between the bearing element and the receiving space is formed according to an embodiment of the invention by a toothing complementary elevations and depressions in a surface regions of the bearing element and in a surface region of the receiving space. The surface areas which form the form fit may be formed on the circumferential surface of the roller-shaped bearing element. For example, the clamping device may act on the two or more parts of the housing surrounding the receiving space to form the positive engagement between the peripheral surface of the roller-shaped bearing element and the adjacent surface area of the receiving space. According to an alternative embodiment, the positive engagement between a surface portion on one or both ends of the cylindrical bearing member and the clamping device, which is provided on the opposite surface of the storage space in the housing. This embodiment makes it possible to produce the housing in the region of the receiving space in one piece, because it is not necessary that the roller-shaped bearing element is surrounded in the circumferential direction by more than 180 ° from the receiving space. The roller-shaped bearing element can be rotatably supported by an axis or by bolts in the axial direction in the receiving space. The form fit for blocking the rotation can act in this embodiment between the receiving space and the bearing element either in the direction parallel offset to the axis of rotation on the end face of the bearing element or in the radial direction on the peripheral surface of the roller-shaped bearing element.
Gemäß einerbevorzugten Ausführungsform ist das Lagerelement in dem Aufnahmeraum des Gehäuses durch einen oder zwei Bolzen drehbar gelagert. Die Bolzen können das Lagerelement auf zwei gegenüberliegenden Seiten des Aufnahmeraums mit dem Gehäuse drehbar verbinden. Gemäß einer bevorzugten Ausführungsform bildet ein Bolzen zwischen dem Lagerelement und dem Aufnahmeraum ein Festlager und ein zweiter Bolzen bildet auf der gleichen Achse, jedoch auf der gegenüberliegenden Seite des Aufnahmeraums, ein Loslager. Unter einem Festlager ist ein Lager zu verstehen, welches eine Bewegung in zwei Freiheitsgraden einschränkt. Dieses Lager lässt nur eine Drehung des Lagerelements gegenüber dem Aufnahmeraum zu. Unter einem Loslager ist ein Lager zu verstehen, welches das Lagerelement gegenüber dem Aufnahmeraum nur um einen Freiheitsgrad blockiert. Das Lager sorgt dafür, dass das Lagerelement gegenüber dem Aufnahmeraum drehbar ist und axial verlagerbar ist. Das Loslager kann z.B. dadurch ausgebildet sein, dass ein Bolzen durch eine Seitenwand des Gehäuses in den Aufnahmeraum hineingreift und in dem Lagerelement in eine lose eingelegte Mutter eingeschraubt ist, welche in axialer Richtung des Lagerelements verschiebbar ist, aber gegen eine Drehung gegenüber dem Lagerelement durch einen Formschluss gesichert ist. Das Loslager hat den Vorteil, dass es sich bei einer thermischen Ausdehnung des Gehäuses gegenüber dem Lagerelement keine mechanischen Verspannungen zwischen den Bolzen und dem Lagerelement ergeben.According to a preferred embodiment, the bearing element is rotatably mounted in the receiving space of the housing by one or two bolts. The bolts may rotatably connect the bearing member to the housing on two opposite sides of the receiving space. According to a preferred embodiment, a bolt between the bearing element and the receiving space forms a fixed bearing and a second bolt forms on the same axis, but on the opposite side of the receiving space, a floating bearing. Under a fixed bearing is a camp to understand, which limits a movement in two degrees of freedom. This bearing allows only one rotation of the bearing element relative to the receiving space. Under a floating bearing is to be understood, which blocks the bearing element with respect to the receiving space by only one degree of freedom. The bearing ensures that the bearing element is rotatable relative to the receiving space and is axially displaceable. The floating bearing may be formed, for example, by a bolt engages through a side wall of the housing in the receiving space and is screwed into the bearing element in a loosely inserted nut which is displaceable in the axial direction of the bearing element, but against rotation relative to the bearing element by a Positive locking is secured. The floating bearing has the advantage that, given a thermal expansion of the housing relative to the bearing element, there are no mechanical stresses between the bolts and the bearing element.
Gemäß einer bevorzugten Ausführungsform der Erfindung weisen wenigstens zwei der verschiedenen Winkelstellungen, in denen das Lagerelement blockierbar ist, einen maximalen Winkelabstand von wenigstens 90°, insbesondere bevorzugt von wenigstens 105° auf. Dadurch ist es möglich, dass die Leuchte sowohl an einem vertikalen als auch an einem horizontalen Mastausleger montiert werden kann. Der Winkelabstand zwischen den zwei Winkelstellungen ist ausreichend, um das Leuchtengehäuse bei waagrechtem und bei senkrechtem Mastansatz in die gewünschte Lage gegenüber der zu beleuchtenden Fläche zu bringen. Bei dieser Ausführungsform ist es bevorzugt, dass jeweils benachbart zu den zwei Winkelstellungen, welche einen Winkelabstand von wenigstens 90° aufweisen, in geringerem Winkelabstand, beispielsweise in einem Winkelabstand von weniger als 8° oder weniger als 4°, Winkeleinstellungen vorhanden sind, in denen das Lagerelement ebenfalls blockierbar ist. Dadurch ist es möglich, eine Feinjustierung des Leuchtengehäuses sowohl an einem vertikalen Mast als auch an einem etwa horizontalen Mastausleger vorzunehmen. Beispielsweise kann vorgesehen sein, dass die Leuchte in Schrittweiten von 1° bis 8° von -3° bis 15° und von 75° bis 105° einstellbar ist.According to a preferred embodiment of the invention, at least two of the various angular positions in which the bearing element is blockable, a maximum angular distance of at least 90 °, more preferably at least 105 °. This makes it possible that the lamp can be mounted on both a vertical and a horizontal mast boom. The angular distance between the two angular positions is sufficient to bring the luminaire housing with horizontal and vertical mast approach in the desired position relative to the surface to be illuminated. In this embodiment, it is preferred that each adjacent to the two angular positions, which have an angular distance of at least 90 °, at a smaller angular distance, for example at an angular distance of less than 8 ° or less than 4 °, angle settings are present, in which the Bearing element is also blocked. This makes it possible to make a fine adjustment of the lamp housing both on a vertical mast and on an approximately horizontal mast boom. For example, it can be provided that the lamp in increments of 1 ° to 8 ° from -3 ° to 15 ° and from 75 ° to 105 ° is adjustable.
Gemäß einer bevorzugten Ausführungsform der vorliegenden Erfindung weist das Lagerelement einen Ansatz mit einer Vertiefung auf, in der ein Ende des Masts mittels einer Klemmverbindung reibschlüssig oder formschlüssig gehalten werden kann. Beispielsweise kann das Lagerelement einen Ansatz mit einer etwa zylindrischen Vertiefung aufweisen, welche auf das Ende des Leuchtenmastes aufgesteckt werden kann und mit einer seitlichen Klemmvorrichtung daran festgelegt wird. Diese Verbindung hat den Vorteil, dass auch die Winkelposition zwischen dem Mast und dem Lagerelement eingestellt werden kann. Bei dieser Ausführungsform kann die Leuchte um zwei zueinander senkrechten Achse in jede Raumrichtung ausgerichtet werden. Alternativ kann der Leuchtenmast mit einem Ansatz an dem walzenförmigen Lagerelement durch vorgehende Bohrungen in einer oder in mehreren auszuwählenden Positionen verschraubt sein.According to a preferred embodiment of the present invention, the bearing element has a projection with a recess in which one end of the mast can be held by means of a clamping connection frictionally or positively. For example, the bearing element may have a projection with an approximately cylindrical recess, which can be plugged onto the end of the lamppost and is fixed thereto with a lateral clamping device. This connection has the advantage that the angular position between the mast and the bearing element can be adjusted. In this embodiment, the lamp can be aligned about two mutually perpendicular axis in each spatial direction. Alternatively, the lamppost can be bolted to a projection on the roller-shaped bearing element by preceding holes in one or more positions to be selected.

Gemäß weiteren nicht in den Figuren dargestellten Ausführungsformen der Erfindung können auch andere Arten von Formschlusselementen zwischen dem Lagerelement und dem Gehäuse oder einem mit dem Mastansatz verbundenen Bauteil vorgesehen sein. Beispielsweise kann das Lagerelement an seinem Umfang sägezahnförmige Erhebungen aufweisen, die in komplementäre Vertiefungen des Gehäuses oder des Gegenlagers eingreifen. Sägezahnförmige Erhebungen bzw. Vertiefungen haben den Vorteil, dass sie beim teilweise Lösen der Klemmeinrichtung in eine Richtung leicht gegeneinander gedreht werden können, während die andere Richtung noch blockiert bleibt. Beispielsweise kann die sägezahnförmige Vertiefung so ausgebildet sein, dass das Leuchtengehäuse bei einer zum Teil gelösten Klemmverbindung gegenüber der horizontalen weiter geneigt werden kann, ohne dass das Leuchtengehäuse durch die Schwerkraft sich selbständig zurückdreht.According to other embodiments of the invention not shown in the figures, other types of positive locking elements may be provided between the bearing element and the housing or a component connected to the mast extension. For example, the bearing element may have sawtooth-shaped projections on its circumference, which engage in complementary recesses of the housing or of the anvil. Saw-tooth-shaped elevations or depressions have the advantage that they can be easily rotated against each other when partially releasing the clamping device in one direction, while the other direction is still blocked. For example, the sawtooth-shaped recess may be formed such that the luminaire housing can be tilted further with respect to the horizontal in the case of a partially released clamping connection, without the luminaire housing turning back by gravity independently.
